摘要: An initialization vector (IV) is employed to decrypt a block of a stream that has been encrypted with Cypher Block Chaining (CBC) encryption, without requiring decryption of previous blocks within the stream. For example, a listener who accesses a distribution point to retrieve encrypted content authenticates himself to an application server that regulates access to encrypted content on the distribution point, and responsively receives a key. The listener then requests access to a reference point within the encrypted content stream somewhere after its beginning (e.g., using preview clips). The distribution point relates the reference point to a corresponding block of the encrypted stream, and identifies an IV previously used for encryption of that block. The distribution point provides the associated encrypted block of content and the IV to the listener to enable mid-stream rendering of the encrypted content, without requiring the listener to decrypt previous blocks within the encrypted stream.

摘要: Systems and methods for generating suggestions based on group criteria. A device may act as a proxy for a group and scan information from other devices in the group. The proxy device may then transmit the scanned information to a remote resource. The remote resource may obtain preference information based on profile information, for devices that are determined to be registered with a service, and based on inquiry responses for unregistered devices. The preference information may be compiled into group criteria that may be employed in making one or more suggestions to the group. If the group selects one of the suggestions then the remote resource may make arrangements based on the selection. Otherwise, additional suggestions may be provided to the group. The remote resource may also monitor the group and continue to make suggestions accordingly.

摘要: An embodiment of the invention provides context aware messaging. Such context aware messaging may include delivering communications (e.g., coupons, promotions) to mobile device users based on the device user's context (e.g., physical location, time of day and week, habits, tendencies, and the like). An embodiment includes sensing an environmental condition for a user; wirelessly communicating the sensed condition to a remotely located node; and receiving a context based communication in response to communicating the sensed condition to the remotely located node; wherein the context based communication corresponds to the sensed environmental condition. Other embodiments are described herein.

摘要: Techniques are provided for displaying a uniform resource locator (URL) to assist a user in determining whether a URL destination is what the user expects. A link is presented for selection to a user, and a URL corresponding to the link is accessed. A portion of the URL that corresponds to a hostname component of the URL may be identified, and the URL may be displayed. The hostname component of the URL is visually distinguished from other components of the URL. In addition to or as an alternative to displaying the URL and visually distinguishing the hostname component, a warning message relating to the hostname portion of the URL may be displayed. The techniques may be implemented as a software plug-in or in any type of software application that is capable of recognizing URLs.
